Melanie, cool project! Bet it does take a lot of time to put together. Are you a teacher?
Are you nervous about how your DH's family will respond to the pregnancy? We told close family and friends as soon as we knew (4 weeks) but saved the coworkers til they started figuring it out on their own, around 8 weeks. (I was eating crackers at work and people knew we were "trying"... they put two and two together and word got out. I mean, who eats starchy carbs in broad daylight anymore unless they've got morning sickness, right? )
However, telecommuting also means I haven't had to tell any of my coworkers yet. Unlike you, the other day when all I could eat were Triscuits, nobody but the DH saw.
We are nervous about telling the DH's Mum because she will go nuts and start shopping. I know that sounds odd but we are quite anti-consumerist people, preferring to shop second-hand and don't like owning a lot of stuff and live in a small (although perfectly accommodating apartment). When his older brother & wife started having kids they begged her not to go nuts buying things and she got really offended and said she could do what she wanted for her grandchildren. Christmas, needless to say, is a bit of a nightmare with the nephews crying because they don't want to open any more presents! Talk about an odd problem to have eh? However the DH's brother & wife also put a lot of the presents away to donate to kids who need them and the nephews don't even mind. Most of the presents break within the first couple months anyway. We just wish they would save their money and buy a cow for a village or something. We think spending time with your grandkids is much better than just spending money on them, they do that too but feed the kids full of sugar and get them really wired and I can tell it is hard for the DH brother & wife to calm them down after a couple days a grandmas. Really, I don't even like talking about this kind of thing because I know how ungrateful it makes us sound. His parents aren't bad people, but he has a hard time getting along with them.
